Appli-cation filed February 18, 1914. Serial No. 819,505. i

of which the following is a specification.

This invention relates to an improved breast strap, and the principal object of the invention isto provide a breast strap with Van improved means for adjustably connecting the two sections of the strap, the connecting pin being so constructed that the entire strain is not brought against the lower edge of the opening in which the pin is placed thereby preventing danger of the opening being torn.

Another object of the invention is to provide the lower section of the breast strap with an improved construction so that the connecting pin will be securely held in place and so that the section of the breast strap will not be very quickly worn out due to frictional engagement with the breast yoke.

This invention is illustrated in the accompanying drawings wherein- Figure 1 is an elevation of the improved breast strap mounted upon a breast yoke, one end of which is shown; Fig. 2 is a longitudinal sectional view taken along the line 2-2 of Fig. 1; Fig. 3 is an elevation of the metallic liner which is mounted in the eye of the lower section of the breast strap. This breast strap comprises the upper and lower sections 10 and 11 which are adjustably connected together by means of a pin carried by the lowerv section and passed through a selected opening formed in the upper section. The lower section is mounted upon the breast yoke 12 and is held in place by means of the usual securing member 13 whereas the upper section is carried by the collar which passes through the loop 14 of the upper section.

The upper section 10 is formed from a strip of leather which is double intermediate its length and sewed together as shown in Fig. 1. The stitches do not extend the full length of the upper section but terminate short of the upper end so that the loop 14 through which the collar passes will be formed. Openings 15 arc formed in the up per section and extend longitudinally of the upper section. In the drawing there has been shown four of these openings, but it is of course obvious that the number will be changed according to the size of the breast strap. Protecting plates or washers 16 which are formed of any suitable material such as leather or light metal are secured to the upper section by means of suitable rivets as shown and surround the openings 15 to protect the upper section of the breast yoke from being worn through by frictional engagement of the head formed upon the coupling pin carried by the lower section.

The lower section is formed from two leather strips 17 and 18 which are placed one upon the other and doubledto provide a loop through which the breast yoke passes. The metallic liner 19 fits in the loop of the lower section and is held in place by means of the side flanges 20 which engage the side edges of the two strips 17 and 18 and thus prevent the liner from moving transversely through the loop. The coupling pin has its shank 21 positioned as shown at Figs. 1 and 2 and secured by rivets 22. The stem 23 which passes through openings 15 is curved as shown in'Fig. 2 so that when the arms of thehead 24 engage the washer 16, the curved stem will only engage the lower edge portion of the opening 15 through which it passes. By having this stem curved, instead of being straight, there is thus accomplished a two point contact which prevents thestem from striking squarely against the lower end of the opening 15 thus preventing any danger of the upper section being torn through from one opening to another.

This breast yoke is operated in a very simple manner. The lower section is permanently connected with the breast yoke and the upper section is mounted upon the collar. After the harness has been placed upon the horse and the horse attached to the vehicle, the Vhead 241 is passed through one of the openings 15`and its sections are then turned to extend parallel as shown at Fig. 2 with the head 24: engaging one side of the upper section and the curved stem engaging the lower end ofthe opening at the opposite side of the upper'section. This breast yoke canV thereforevstand a` great deal of strain without breaking since the strain is not placed entirely upon the lower end of the opening, but is evenly distributed between the edge of the opening engaged by the stem and the body portion of the upper section where it is engaged by the arms of the head 24. A tug could be connected with a swingletreeby means of the saine construction, the

tug having its free end provided with the eyesand the engaging elements which Carry 'the stems 23 being mounted upon the ends ing therefrom7 and a coupling pin provided l with a shank secured between the end portions of the strip forming the lower section and having a longitudinally curved stern arranged to extend from the shank through one of the openings of the upper section and terminating in a cross head arranged to project upon opposite sides of the stem and of the openings through which the stem passes and to engage the face of the upper section to releasably connect the upper and lower sections, the arrangement being such that the upper section extends substantially parallel to the ends of the strip forming the lower section.

In testimony whereof I affix my signature in presence of two witnesses.
